SAW-FILING DEVICE.

SPECIFICATION forming part of Letters Patent No. 493,445, dated March14, 1893.

Application filed June 20, 1892- SerialNo. 437,328. (No model.)

To all whom it may concern.-

Be it known that I, MARVIN J. PAGE, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented-certain new and useful Improvements in Saw-Filing Devices, ofwhich the following is a specification,reference being had therein tothe accompanying drawings.

This invention relates to new. and useful improvements in a saw filingdevice, and the invention consists in the peculiarconstruction,arrangement and combination of the various parts.

In the drawings, Figure l is a plan view of the device showing itapplied as in use. Fig. 2 is a detached perspective View of the fileholding frame. Fig. 3 is a bottom plan view of the block.

A is a block having a groove B on its upper surface and a series ofintersecting slots C having their crossing point at the bottom of thegroove B, these slots being of suitable size to fit over the toothededge of a saw and act as aguide therefor, and of such depth that the sawwill project up into the groove a sufficient distance to enable me tofile the teeth.

In order to file the teeth I employ a frame slidingly engaged with theblock and carrying a file. This frame consists of a single piece of wirebent to form the two longitudinal bars D D, and the cross bar E havingan eye F formed centrally in the cross bar by twisting the wire. Thelongitudinal bar D passes through a slot in the block while thelongitudinal bar D bears against the edge of the groove. The twolongitudinal bars are connected together at their lower ends by a crossbar or head G, the whole forming a rectangular frame slidingly engagingwith the block adapted to be turned upon one of the bars as a pivot toand from the block.

H is a bearing centrally formed in the cross bar G and of suitable sizeto enable a file to be passed therethrough, and I a set screw enteringsaid bearing adapted to bear against the file, or handle J, in which theend of the file is adapted to be secured, the upper end of the filebeing held firmly in position by engaging in the eye F at the upper endof the frame. The parts being thus constructed and the saw being engagedin one of the slots the operator taking hold of the frame moves itbackward and forward having previously engaged the saw with one of theteeth he then moves the saw along and engages it with the next one, andso on to the end, insuring perfect evenness in filing, and also enablesme to cut away the entire cutting surface of the file as it may beturned about for the different edges, and the frame maybe reciprocatedthe entire length of the file.

What I claim as my invention is- In a saw filing device, the combinationwith a gage block, of a sliding file holder pivotally secured therein atone side, and consisting of a single piece of wire bent to form parallelside bars and an outer cross bar having its central portion bentinto avertically disposed loop, a cross bar at the opposite end of the frameuniting the inner ends of the side bars, and formed with a central eye,and-a fastener at the eye arranged to engage the file handle whenadjusted, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.
